How long does the fledging period last for Yellow-eyed Penguin chicks?
Answer
Around 100 days
The fledging period for Yellow-Eyed Penguin chicks, defined as the time until they are independent enough to depart for the sea, is comparatively long for penguins, stretching out to approximately 100 days. This extended maturation time, coupled with the typical clutch size of only two eggs per breeding attempt, contributes significantly to the species' vulnerability. This slow reproductive rate means there is limited resilience to high rates of reproductive failure, placing immense importance on the successful rearing of each individual chick.
